T0 all whom t may concern: A

Be it known that I, PETER Gr.Y Jnooson, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Razor-BladeHold ers, of which the following is a full, clear, concise, and exact description. y

My invention relates to razor blade holders and is of particular service in the formation of holders to be used in holding the blades that arev to be honed, though the invention is not to be limited to this use.

My invention has for one of its objects the provision of improved means for limiting' the extent to which the blade holding clamp may swing with reference to the handle carrying it. I employ a motion limiting connection engaging both the handle and the clamp.

My invention has'for another of its objects the provision of improved mechanism for forcing the jaws of the blade holding clamp into engagement with the blade to be held thereby7 and to this end I employ' transverse continuations upon the jaws and means acting upon these continuations for the purpose stated. Certain of the claims upon my invention are contained in my original application, Serial No. 147,291, filed February 8, 1917, and of which the present application is a division.

I will explain my invention more fully by reference to the accompanying drawing showing the preferred embodiment thereof and in which Figure 1 is a view in side elevation of a razor blade holder as I preferably make it; Fig, 2 is a plan view; Fig. 3 is a view on line 33 of Fig. 2; Fig. al is a view similar to Fig. 3 but with the jaws of the blade holding clamp open; Fig. 5 is a view on line 5 5 of Fig. 3; Fig. 6 is a view on line 6 6 of Fig. 1; and Fig. 7 is a view on line 7-7 of Fig; 5.

Like parts are indicated by similar characters of reference throughout the different j figures.

forward ends. This rod is preferably of sectional formation, its parts being a sleeve 41 and trunnion screws 5 and 6 entering the bore of the sleeve and in threaded connection with the ends thereof. Each of the jaws has transverse continuations 7 the transverse continuations upon one jaw being interposed betweenfthe transverse continuations upon the other jaw. The tube or sleeve ais' interposed between the continuations upon one jaw and has butt engagement with said 'continuations The vtrunv`nion. screws extend outwardly beyond the clamp and their stems are surrounded by said continuations and the forward ends of the for r branches 3 of the handle, whereby tlie clamp and handle are assembled and the clamp may swing upon the handle at a point between the forward and rear ends of the clamp.

The rear ends of the clamp jaws are pivotally united by a shaft 8 passing therethrough and which shaft carries a roller 9 for supporting the clamp in proper position upon the hone. The extent to which the clamp may swing upon the handle is limited by the connections 10 that are continuations of the shaft S and whose outer ends have lost mot-ion engagement with the handle parts 3, preferably by operating in slots 11. l/Vhen this construction is adopted, the shaft 8 is desirably made in two parts as indicatedin Fig. 5.

The openings in the jaw continuations through which the trunnion screws 5 pass arepreferably in the form of slots extending longitudinallyof the clamp and along which said screws may be moved bodily and longitudinally with reference to the clamp. rIhis may be done by holding the clamp in one hand and the handle in the other and moving the clam toward or away from the handle. When tie clamp is pulled out as far as possible, the screws are at the rear of the slots (Fig. Ll) and these slots are then most out of register and the jaws o-f` the clamp are then farthest apart to permit of the insertion of a blade 12. Nhen the screws are forced to the front ends of the slots, the slots are brought more into register and the jaws are consequently forced together (Fig. 3) to grip the inserted blade 12. The front end of one of the slots is continued laterally of the slot in one direction and the front end of the other slot is continued laterally in lio ters Patentv the following Y 20 an Vopposite direction whereby a locking formation is produced to hold the shaft when the blade is clamped, the shaft'being prevented from working 'baokwardij The rear ends of the slots Vmay be similarly curled to cause the shaft to be held when the jaws are separated but such formation orl the rear ends of the slotsris not essential. TheVV to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, 'but having thus described my invention I claim as new and desirev to secure by Letl. A vrazor blade-holder including a pair Copies of this patent may be obtained for of jaws having transverse eontinuations provided with longitudinal slots that `are out of register when the jaws are open; and arod I Vpassing through said slots and movable 1ongitudinally thereof to cause said slots to beY moved into register to apply the jaws to the blade 'to be held thereby, '1
